why would you need to test the glock roni conversionvs a stock glock... the barrell length is the same, hence the velocity and expansion.

Sorry, it was a Mechtec 16"bbl that I tested.
As for the number of pages... I know I wrote it down somewhere but I've moved several times since. I wasn't taking any chances of ruining the experiment so I duct taped 4 big phonebooks together and dunked them. Duct taping them good is essential because once they get wet, they expand or want to at least and once you cut the tape to go digging, it'll be hard putting them back together again so just space the rounds out evenly to make the most of the phonebooks.
One other round I tested at point blank range was a 265gr carbine bullet out of my 44mag dessert eagle and it punched through all four books and slammed into the concrete with very little deformation of the bullet. I was rather surprised at that also.

I hate to say it but several times in this thread you have back peddeled when called out on stuff, and then changed your story(s)... frankly I find you funny.
In all fairness it's possible that by "glock conversion" he meant the Mechtech glock conversion.

What he says is perfectly plausible. You do get a longer barrel with the Mechtec units. If he compared both a stock Glock and a Mechtec Glock conversion in terms of penetration tests, then his posts make perfect sense. Why is his assertion so funny to you?
$40 for a pig carcass. Does not get any more realistic. I was at a test facility state side and they went through roughly 80 pigs/h I swear. They were testing various calibers at different distances. Was funny seeing ballistic vests and BDU's on dead swine's but I was amazed with the damage some of these pigs received. What and why they were testing? Who knows. Was invited by a friend while visiting.

If you're still confused, check out post #366. I quoted a guy who made mention of having a Mechtech conversion for his Glock.
regarding pistol velocities in pistol vs pdw vs carbine length barrels.
And since you brought up pistol calibers and phone books....
Thinking you're doing an 'experiment' by taping a bunch of phone books together and getting them wet, and just spacing the rounds out on the same book, is laughable at best.
It's more of a range game than anything and will not give you any meaningful or quantifiable data.
And using carcasses, while a good way to look at wound ballistics and channels, throws too many variables into the mix to accurately gauge the performance of different bullets.

Your graph is interesting but in no way definitive. Since we don't know what powder Federal is using, it's hard to tell what burn rate it is. Comparing the bullet weight and velocity to known reloading data, it's my SWAG that th powder being used is not of the slowest burn rate on par of Blue Dot or AA #7 for examples.
Naturally, if one hand loads with those slower powders, there's likely to be a greater difference in velocity range when using the longer barrels compared to the shorter ones.
I just want to go on record for saying I don't profess to be some kind of Science Major by testing bullet impacts while using phonebooks as my test subjects. Now that that is in the open, it's kind of like testing your car on a rolling dyno and sticking with it once you have a baseline. Whatever you start testing with, stick with it. Sure I could test rounds for penetration on some level 2 but unless you have something soft behind it, what are you gaining??
What i was able to learn and pass on by using wet phonebooks was that bullets did open up just like the pics on the box and by shooting them out of longer barreled guns there was definitley a difference.
I'm not sure what exactly you're trying to get at with your graph, though informative, there are just too many variables to take into consideration but as long as you can accept that as well, we're all on the same page. If you hand load, you can agree.

Or we can talk about how 300 Blackout is getting more and more affordable with the availability of brass through All Weather Arms in the States.

Problem solved!
This thread was dead months ago until I posted here to revive it. Did it ever occur to you that there's only so many CGN members out there with AR PDW builds and that most of them have likely alread posted here already?
The 9mm discussion is relevant to the thread in the respect that there are 9mm PDW's out there.
If guys only buy guns based on the cool factor or popularity without any tests shown, a lot of these threads wouldn't last long based on pics alone. This isn't just a gun #### site. There are some of us that care whether or not length of barrel or weight of bullet works for guys that buy these guns. If you don't like it, find pics of guns from other sites or somewhere on the web and fill these threads with them instead of complaining that there aren't enough pics.
Agreed but there are also those that don't want to post because of the poor feedback and ridicule and seen in just this topic alone and there are those who don't want to post because they don't trust the people watching this forum.
This topic as listed states: PDW builds, let's see them and show results. I guess that if your not part of the in crowd who have read the PDW bible where it clearly states exactly what a PDW by definition required (by name brand) and for how much and what color your not worthy. I wish that I never posted in the first place and am reserved with future postings because of the a**holes on this forum.
It's pretty bad that a person has to be classified as a noob or get ridiculed if they "as what the expert expresses" ask a simple question get jumped on as soon as he starts with the same passion or interest that we all have. I'm going to speak for those and reply with f**k you and your guns and your all ignorant a**holes. A community is welcoming and invites more to it's family openly in order to growin popularity.
Remember. The public view is always louder and if they are not welcome don't be mad if they don't welcome you. If your too stupid to understand this simple statement it's best that you STFU! If you have nothing worth saying don't say anything.
Anyone who states that they are a professional and requires or demands recognition is unprofessional.
Do you really think that I will be affected by your responses to the above stated? Can the gun community really afford to lose even 1 member? Treat others like you want to be treated to all of you and do your part to grow the community and involve all that are interested and grow the common goal. sure you can sell to a regular but can you sell to a new person? Can you invite someone in with a bad attitude and disrespect?
Naysayers are this community's worst ally.
Why have we lost our rights in the country as legal law abiding gun owners? Because we have lost respect for others!!! Put in the effort and grow the community! Each and everyone of you!! let me explain to the ignorant in easy language. An ex smoker is the worst critic! An ex gun owner is a gun owners worst enemy!
Military, police men, and other professionals all have 1 thing in common. Comradery and putting back into the community for the greater of the whole! Put them in public lol they are just people making a living in order to live till they die. So Saputin, idk if Bigred was in the sand box, or panda dude is a cop. Why should I? Do they deserve my time? Do they care that I have done my part with todays technology and finding more effecient ways to pull energy from the ground so they can fill their car up with fuel and supply electricity to their home? No!
I sure didn't deserve their attention until I backed down and showed some respect even though I never attacked them. Learn to not be a loud mouth.
Remember this for the rest of your lives!
if tour too strong to help the weak your not strong at all!
It's not my graph.
It's what ever Federal used in their Factory loading.
Don't worry, you don't have to go on record for that. It's very apparent from your posts that you're no science major.
You can get the bullets to open up by shooting them into water as well. And any difference is just by chance when you use the same books for more than 1 round. The consistency is no longer the same after the first round has disrupted the tape you've used and gone through the paper, it doesn't matter if you 'space out the rounds'. A Science Major would know that.
For variables regarding the velocities in the above chart, sure, atmospheric pressure, temperature, elevation, etc. But as long as it was the same day and temperature with ammo from the same lot, the variables are reduced greatly, for those barrels used on that day (different barrels will produce different results, but it would be a good baseline, just like reloading data from books is a good baseline, and why you never start with the max load when reloading).
The guys that care whether the rounds work in 'these' guns will have used data from a reputable source or lab after testing that used proper and accepted medium, not from some guy on the internet shooting into wet phone books.

Lol
What a joke.
On that we agree.
